Polyamines are organic compounds that are involved in essential cellular processes, such as DNA stabilization, protein synthesis, and cell signaling. They are crucial for maintaining cellular homeostasis and regulating gene expression.
What is Polyamine Biosynthesis Pathway?
In Bacteria, the pathways of polyamine biosynthesis start with the amino acids L-lysine, L-ornithine, L-arginine, or L-aspartic acid. Some of these polyamines are of special interest due to their use in the production of engineering plastics (e.g., polyamides) or as curing agents in polymer applications. At present, the polyamines for industrial use are mainly synthesized on chemical routes. However, since a commercial market for polyamines as well as an industry for the fermentative production of amino acid exist, and since bacterial strains overproducing the polyamine precursors L-lysine, L-ornithine, and L-arginine are known, it was envisioned to engineer these amino acid-producing strains for polyamine production. Only recently, researchers have investigated the potential of amino acid-producing strains of Corynebacterium glutamicum and Escherichia coli for polyamine production.

The polyamine biosynthesis pathway is a series of enzymatic reactions that occur within cells to synthesize polyamines. It involves the conversion of precursor molecules, such as ornithine and arginine, into polyamines like spermidine and spermine. The pathway consists of several key enzymes, including ornithine decarboxylase, S-adenosylmethionine decarboxylase, and spermidine synthase. These enzymes catalyze the sequential addition of amino groups to precursor molecules, resulting in the production of polyamines.
What is Polyamine Biosynthesis Strain Engineering?
Polyamine Biosynthesis Strain Engineering is a technical approach that involves the modification of microbial strains to enhance the production of polyamines. Polyamines are organic compounds that play important roles in cellular processes. In this process, microbial strains are carefully selected based on their genetic background and growth characteristics. Advanced genetic engineering techniques, such as gene overexpression or knockout, are then used to optimize the expression of key enzymes involved in the polyamine biosynthesis pathway. The engineered strains are further optimized through culture conditions and undergo screening and selection to identify high-performing strains. The final step involves scaling up the production process and fine-tuning it according to specific requirements. This approach offers expertise, advanced genetic engineering techniques, and a collaborative approach to provide customized polyamine biosynthesis services.
